Description

  The present invention relates to an electrolyzed water production apparatus having an intermediate chamber for containing an aqueous electrolyte solution, an electrolyzed water production method using the electrolyzed water production apparatus, and electrolyzed water obtained by the electrolyzed water production method.

  As a general electrolyzed water generating device, there are a one-tank type and a two-tank (chamber) type generating device. For example, when a one-tank generator is used, an aqueous electrolyte solution such as saline is injected into a tank to dispose an anode plate and a cathode plate, and the anode plate and the cathode plate are energized to undergo an electrolysis process. Alkaline electrolyzed water containing sodium chloride is produced. Further, in the electrolysis process, harmful trihalomethane is generated and sodium chloride remains as it is.

  Moreover, as a 2 tank (chamber) type production | generation apparatus, the thing of the structure disclosed by Unexamined-Japanese-Patent No. 2005-329375 (document 1) is well-known, for example. This two-chamber generator forms two electrolysis chambers that are opposed to each other by partitioning an intermediate portion of one tank with an ion-permeable diaphragm, and provides raw water supply means and electrolyzed water extraction means in each electrolysis chamber, One electrolytic type is provided with an anode electrode and a chloride aqueous solution (brine) supply means, and the other electrolytic chamber is provided with a cathode electrode. Then, by applying a required voltage to each electrode and performing an electrolysis process, acidic electrolyzed water containing chlorine gas and sodium chloride is obtained in the electrolytic method on the anode side, and hydrogen gas and alkaline electrolysis are obtained in the electrolysis chamber on the cathode side. Water is obtained.

As an apparatus for producing electrolyzed water that does not contain sodium chloride, for example, a three-tank electrolyzer disclosed in Japanese Patent Laid-Open No. 2000-246249 (Document 2) is known. This three-tank electrolysis apparatus has a structure in which an anode chamber and a cathode chamber are provided on both sides of the intermediate chamber via ion exchange membranes and electrode plates. The intermediate chamber is filled with a high concentration electrolyte aqueous solution, for example, 10% potassium chloride or sodium chloride aqueous solution. Further, for example, tap water is passed through the anode chamber and the cathode chamber, and both electrode plates are energized and subjected to an electrolysis step, so that electrolysis water containing no sodium chloride, that is, pH 2.0 to 3. in the anode chamber. About 0 acidic electrolyzed water is produced. On the other hand, alkaline electrolyzed water having a pH of about 10.0 to 12.0 is generated in the cathode chamber.

  However, in the generation of electrolyzed water disclosed in the above-mentioned document 1, in order to increase electrolysis efficiency, salt water is supplied to one electrolysis chamber (anode side) to perform electrolysis. The acidic electrolyzed water produced in the electrolytic chamber on the anode side contains not only hypochlorous acid but also sodium chloride, which causes vaporization of chlorine gas due to equilibrium movement. Accordingly, since hypochlorous acid and the like are vaporized in a short time, it is difficult to ensure the bactericidal power required in the acidic electrolyzed water for a long period of time, and there is a problem that its use is limited.

  In addition, the method for producing electrolyzed water disclosed in the above-mentioned document 2 is that the electrolysis chamber has three tanks, an aqueous electrolyte solution such as saline is stored in the center electrolysis chamber, and the anode and cathode electrolysis chambers on both sides. Accommodates electrolyzed tap water or purified water via a water purifier. It is superior in that it can efficiently generate acidic electrolyzed water and alkaline electrolyzed water that does not contain sodium chloride, even when the voltage, current, and time are small, by storing the aqueous electrolyte solution in the central electrolysis chamber. . However, since all of the three-tank electrolytic chambers are batch-type, they are not only mass-productive, but are mixed or blended with acidic electrolyzed water and alkaline electrolyzed water to make it weakly acidic, neutral or weakly alkaline. There is no idea of producing electrolyzed water containing hypochlorous acid adjusted for pH.

  Incidentally, acidic and alkaline electrolyzed water is generated by an electrolysis method using the two-chamber or three-chamber electrolyzer according to the known technique, and the effective chlorine concentration of the generated electrolyzed water is set to a predetermined value. It is difficult to adjust the pH value to weak acidity or weak alkalinity while maintaining the above range. In addition, in the electrolysis method using a two-chamber or three-chamber electrolytic cell, sodium hypochlorite was not substantially produced.

  An object of the present invention is to provide an apparatus for producing electrolyzed water, a method for producing electrolyzed water, and electrolyzed water that can efficiently generate weakly acidic or weakly alkaline electrolyzed water.

1. Electrolyzed water production apparatus The electrolyzed water production apparatus according to the present invention comprises:
An anode chamber provided with an anode electrode;
A cathode chamber provided with a cathode electrode;
An intermediate chamber provided between the anode chamber and the cathode chamber and containing an aqueous electrolyte solution;
A first diaphragm comprising an anion exchange membrane separating the anode chamber and the intermediate chamber;
A second diaphragm comprising a cation exchange membrane separating the cathode chamber and the intermediate chamber,
The anode chamber and the cathode chamber communicate with each other;
Water is configured to be movable in both directions between the anode chamber and the cathode chamber.

  The inventor of the present application has found that, in the production of electrolyzed water, acid water generated in the anode chamber is mixed into the cathode chamber, so that scale does not adhere to the cathode of the cathode chamber. Therefore, according to the present invention, since the anode chamber and the cathode chamber communicate with each other, the scale does not adhere to the cathode of the cathode chamber, and the process of cleaning the scale can be eliminated or the number of times can be reduced. Long continuous operation is possible.

  In the present invention, the anode chamber and the cathode chamber may be separated by a partition wall, and a communication hole may be provided in the partition wall to communicate the anode chamber and the cathode chamber. Thereby, since it is not necessary to separately form a communication path, a compact electrolyzed water production apparatus can be realized.

  In the present invention, a distribution ratio adjusting valve for determining a distribution ratio between the amount of water flowing in the anode chamber and the amount of water flowing in the cathode chamber can be provided. By having this distribution ratio adjusting valve, the ratio of the introduction amount of the anode chamber and the cathode chamber can be adjusted, and pH adjustment becomes easy.

  The present invention may include a first discharge valve that adjusts a discharge amount for discharging the liquid in the anode chamber and a second discharge valve that adjusts a discharge amount for discharging the liquid in the cathode chamber. Thereby, by adjusting the opening / closing amount of the first discharge valve and the second discharge valve, it is possible to adjust the amount of acid water generated in the anode chamber mixed into the cathode chamber.

  In the present invention, a first liquid supply port for supplying liquid to the anode chamber, a second liquid supply port for supplying liquid to the cathode chamber, and a first for discharging the liquid in the anode chamber. A discharge port and a second discharge port for discharging the liquid in the cathode chamber, wherein the first liquid supply port is provided in an upper portion of the anode chamber, and the second liquid supply port is The first discharge port may be provided in a lower portion of the anode chamber, and the second discharge port may be provided in a lower portion of the cathode chamber.

  According to this, the liquid introduced into the anode chamber is directed from top to bottom, the contact time between the gas generated in the anode chamber and the introduced liquid is increased, and a gas-liquid reaction can be surely caused.

  In the present invention, the height of the anode chamber may be larger than the width of the anode chamber in the direction orthogonal to the anode. The ratio of the height of the anode chamber to the width of the anode chamber (height / width) can be, for example, 1.5 or more, preferably 1.5 to 5.0. According to this, since the gas generated in the anode chamber moves upward as the height of the anode chamber increases, the time for the gas-liquid reaction with the liquid introduced into the anode chamber can be lengthened.

  In the present invention, the aqueous electrolyte solution contains chloride ions, and the electrolyzed water production apparatus is particularly useful for producing electrolyzed water containing hypochlorous acid.

  In the present invention, the anion exchange membrane may be provided with micropores for allowing the aqueous electrolyte solution to pass therethrough. According to this, the positive ions of the aqueous electrolyte solution also move through the micropores of the anion exchange membrane. In particular, it is useful for producing a mixed water of hypochlorous acid and sodium hypochlorite.

  In the present invention, the diameter of the fine holes may be 30 to 80 μm.

  The cathode may be covered with a sheet that is permeable to water. By covering the cathode with a sheet that is permeable to water, the electrolyzed water stays in the vicinity of the cathode. For this reason, the charge amount with respect to the water staying in the vicinity of the cathode 32 increases. As the amount of charge for water increases, the deposition of cation-based scales is further reduced.

  In the present invention, a communication path connecting the anode chamber and the cathode chamber can be provided. According to the communication path, there is an advantage that it is easy to grasp the amount of water going back and forth between the anode chamber and the cathode chamber. In addition, an open / close amount adjustment valve may be provided in the communication path. With this open / close amount adjusting valve, the amount of water traveling between the anode chamber and the cathode chamber can be adjusted. The opening / closing amount adjusting valve is a concept including a simple opening / closing valve.

  In the present invention, a first gas vent for venting the gas generated in the anode chamber can be provided. Thereby, the gas generated in the anode chamber can be discharged, and the instability of the flow rate due to the gas can be prevented.

  In the present invention, a first gas vent for venting the gas generated in the cathode chamber can be provided. Thereby, the gas generated in the anode chamber can be discharged, and the instability of the flow rate due to the gas can be prevented.

  In the present invention, the electrode may be provided with a punching hole and a claw electrode portion extending from one side of the punching hole. Thereby, even if it is an electrode which has a punching hole, electrolysis efficiency can be improved, without reducing an electrode area. The nail electrode portion may be formed by leaving a portion punched during punching without being cut out. Thereby, the electrode which has a punching hole and a nail | claw electrode part can be formed easily.

  In the present invention, an open / close valve for determining whether or not to supply water to the anode chamber may be provided. In an ordinary electrolysis apparatus, electrolysis cannot be performed unless water is supplied to both the anode chamber and the cathode chamber. However, since the anode chamber and the cathode chamber communicate with each other in the present invention, even if this open / close valve is closed, water is supplied to the anode chamber through the cathode chamber, which is not possible with a normal electrolytic apparatus. Electrolysis is possible. For example, when this open / close valve is closed and electrolyzed water is discharged only from the anode chamber side, electrolyzed water having strong acidity can be generated.

  In the present invention, an open / close valve for determining whether or not to supply water to the cathode chamber may be provided. In an ordinary electrolysis apparatus, electrolysis cannot be performed unless water is supplied to both the anode chamber and the cathode chamber. However, since the anode chamber and the cathode chamber communicate with each other in the present invention, even if this on-off valve is closed, water is supplied to the cathode chamber through the anode chamber, which is not possible with a normal electrolytic apparatus. Electrolysis is possible. For example, when this open / close valve is closed and electrolyzed water is discharged only from the cathode chamber side, electrolyzed water having strong alkalinity can be generated.

  According to this, even if the substance (for example, hypochlorous acid) generated in electrolysis moves to the cathode, it moves mainly through the communication hole on the discharge side, so that secondary electrolysis is suppressed in the cathode chamber. be able to.

  In the present invention, the intermediate chamber may be divided into a plurality of compartments in a direction in which the anode and the cathode extend, and an electrolyte or an aqueous electrolyte solution supply unit may be provided in each of the plurality of compartments.

2. Method for Producing Electrolyzed Water The method for producing electrolyzed water of the present invention is a method for producing electrolyzed water using the electrolyzed water producing apparatus of the present invention, wherein the water produced in the anode chamber and And a step of electrolyzing while mixing with water generated in the cathode chamber.

3. Electrolyzed water The electrolyzed water of the present invention is obtained by the method for producing electrolyzed water of the present invention.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

1. Electrolyzed water production apparatus In this embodiment, an example in which the electrolyzed water production apparatus according to the present invention is applied to the production of hypochlorous acid water is shown.

  FIG. 1 shows a schematic view of an apparatus for producing electrolyzed water (hereinafter referred to as “electrolyzer”). FIG. 2 is a diagram showing partition walls and electrodes between the anode chamber and the cathode chamber.

  The electrolyzer 10 includes an anode chamber 20, a cathode chamber 30, and an intermediate chamber 40. The intermediate chamber 40 is provided between the anode chamber 20 and the cathode chamber 30. A communication hole 52 is provided in the partition wall 50 that separates the anode chamber 20 and the cathode chamber 30. The communication hole 52 is provided around the intermediate chamber 40. The communication hole 52 is configured so that water can move bidirectionally between the anode chamber 20 and the cathode chamber 30.

  The intermediate chamber 40 is filled with an aqueous electrolyte solution. In the electrolytic chamber aqueous solution supplied to the intermediate chamber 40, cations (for example, sodium ions) are supplied to the cathode chamber 30 and anions (for example, chloride ions) are supplied to the anode chamber 20. The aqueous solution that has passed through the intermediate chamber 40 may be returned to the electrolyte aqueous solution supply source 80, and the aqueous electrolyte solution may be reused and circulated, or the consumed amount of electrolyte may be added to the intermediate chamber 40. Examples of the aqueous electrolyte solution include chloride salt aqueous solution (sodium chloride aqueous solution and potassium chloride aqueous solution). The concentration of the aqueous electrolyte solution can be, for example, the saturation concentration of the electrolyte.

  The intermediate chamber 40 and the anode chamber 20 are separated by a first diaphragm 24 made of an anion exchange membrane. Since the first diaphragm 24 is made of an anion exchange membrane, the cations in the intermediate chamber 40 do not pass through the first diaphragm 24 and only the anions selectively pass through the first diaphragm 24. . As the anion exchange membrane applied to the first diaphragm 24, a known one can be applied.

  The intermediate chamber 40 and the cathode chamber 30 are separated by a second diaphragm 34 made of a cation exchange membrane. Since the second diaphragm 34 is made of a cation exchange membrane, the anions in the intermediate chamber 40 do not pass through the second diaphragm 34, but only cations selectively pass through the second diaphragm 34. . As the cation exchange membrane applied to the second diaphragm 34, a known cation exchange membrane can be applied.

  A diaphragm fixing frame (not shown) may be provided between the first diaphragm 24 and the second diaphragm 34.

  The cathode 32 is connected to the − side of the DC power supply 70, and the anode 22 is connected to the + side of the DC power supply 70. The DC power supply 70 is configured to be able to arbitrarily set its voltage and current. For example, the DC power source 70 can be arbitrarily selected in the range of 5 to 20 volts, and the current can be appropriately selected and set in the range of 3 to 26 amperes. The anode 22 and the cathode 32 can be made of a mesh-like electrode or an electrode punched with a hole of about 1.5 mm, for example. Note that the punched electrode can have an area removed by punching and an area used as an electrode of, for example, about 50%. A known material can be applied as the material of the electrode.

  The sizes of the anode 22 and the cathode 32 may be asymmetric, that is, the electrode area may be different. Thereby, the electrolysis amount of the anode 22 and the electrolysis amount of the cathode 32 can be changed. Moreover, the acidity of the mixed electrolyzed water can be appropriately adjusted by making the electrode area of the anode electrode different from the electrode area of the cathode electrode. That is, since the electrode area of the anode 22 is larger than the electrode area of the cathode 32, the amount of acidic electrolyzed water generated is larger than the amount of alkaline electrolyzed water generated, so that the acidity can be increased. On the other hand, since the amount of alkaline electrolyzed water generated is larger than the amount of acidic electrolyzed water generated by making the electrode area of the cathode 32 larger than the electrode area of the anode 22, the degree of alkalinity can be increased.

  The electrolyzer 10 is provided with a first water supply port 26 for supplying water to the anode chamber 20 and a second water supply port 36 for supplying water to the cathode chamber 30. The flow path connected to the first water supply port 26 and the second water supply port 36 is configured by branching one flow path. A distribution ratio adjusting valve 60 for adjusting the amount of water distributed to the anode chamber 20 and the cathode chamber 30 is provided at the branch of the flow path. The distribution ratio adjusting valve 60 may also have a supply amount adjusting function for adjusting the amount of water supplied to the electrolyzer 10.

  In addition, the electrolysis apparatus 10 is provided with a first discharge port 28 a that discharges the liquid in the anode chamber 20 and a second discharge port 38 a that discharges the liquid in the cathode chamber 30. Furthermore, the electrolyzer 10 includes a first discharge valve 28b that adjusts the amount of liquid discharged from the first discharge port 28a, and a second that adjusts the amount of liquid discharged from the second discharge port 28a. And a discharge valve 28b.

  The first discharge port 28 a may be provided in the lower portion of the anode chamber 20, and the first water supply port 26 may be provided in the upper portion of the anode chamber 20. Thereby, the water supplied from the first water supply port 26 tends to flow from top to bottom. Therefore, bubbles made of a gas generated at the anode 22 (chlorine when the aqueous electrolyte solution is sodium chloride or potassium chloride) are pushed upward by the water, and it is difficult for the bubbles to rise upward. The time for gas-liquid contact becomes longer, and the reaction to hypochlorous acid can be performed more reliably.

  The anode chamber 20 may be vertically long. Specifically, the height of the anode chamber 20 is preferably larger than the width of the anode chamber 20 in the direction orthogonal to the anode 22. The ratio of the height of the anode chamber to the width of the anode chamber (height / width) can be, for example, 1.5 or more, preferably 1.5 to 5.0. With such a vertically long shape, the time during which the gas (chlorine) generated in the anode chamber 20 contacts with water can be lengthened, and the reaction between chlorine and water can be performed reliably. The cathode 30 may be the same.

2. Operation Next, the operation of the electrolysis apparatus 10 will be described.

  First, the distribution ratio adjusting valve 60 is adjusted, and water is supplied to the anode chamber 20 and the cathode chamber 30. The amount of water is, for example, 0.5 to 1.5 l / min.

  Along with the supply of water, a potential is applied between the anode 22 and the cathode 32 to perform electrolysis. For example, the voltage during electrolysis is 5 to 10 V, and the current is 3 to 10 amperes. In particular, when it is set to 1500 coulombs per liter of the aqueous solution supplied to the cathode chamber 30, preferably 2000 coulombs, it becomes difficult to attach a scale. When a potential is applied between the anode 22 and the cathode 32, the cation in the intermediate chamber 40 (for example, sodium ion when the electrolyte is sodium chloride) passes through the second diaphragm 34 and moves to the cathode chamber 30. The anions in the intermediate chamber 40 (for example, chloride ions when the electrolyte is sodium chloride) pass through the first diaphragm 24 and move to the anode chamber 20.

In the anode chamber 20, chloride ions cause a reaction of the following formula at the anode 22 to generate chlorine.
2Cl ⁻ → Cl ₂ + 2e ⁻
This chlorine further reacts with water to produce hypochlorous acid.
Cl ₂ + H ₂ O → HClO + HCl
On the other hand, in the cathode chamber 30, the following reaction occurs at the cathode.
H ₂ O + 2e ⁻ → 1 / 2H ₂ + OH ⁻
During this electrolysis, acidic electrolyzed water generated in the anode chamber 20 moves from the communication hole 52 provided in the partition wall 50 separating the anode chamber 20 and the cathode chamber 30 to the cathode chamber 30 and is generated in the cathode chamber 30. The alkaline electrolyzed water thus moved moves to the anode chamber 20. Thereby, the acidic water generated in the anode chamber 20 and the alkaline electrolyzed water generated in the cathode chamber 30 are mixed. Further, the acidic water generated in the anode chamber 20 moves to the cathode chamber 30, so that the scale generated in the cathode 32 can be prevented from adhering.

  Further, during this electrolysis, the first discharge valve 28b and the second discharge valve 38b are adjusted to control the amount of electrolyzed water discharged from the anode chamber 20 and the cathode chamber 30.

  By mixing the electrolyzed water discharged from the first discharge port 28a and the electrolyzed water discharged from the second discharge port 38a, the weakly alkaline, neutral or weakly acidic sub-axis according to the present embodiment. Electrolyzed water containing chloric acid is generated.

  Note that one of the first discharge valve 28b and the second discharge valve 38b may be completely closed, and the discharge may be performed only from either the first discharge port 28a or the second discharge port 28b. In this case, mixed water is generated inside the anode chamber 20 or the cathode chamber 30.

3. Operational Effects According to this embodiment, the following operational effects can be achieved.

  (1) In the cathode chamber 20, cations supplied from the intermediate chamber 40 are generally attached to the cathode 32 and scaled. However, the inventor of the present application has found that the scale does not adhere to the cathode 32 by inductively mixing the acidic water produced in the anode chamber 20 into the cathode chamber 30 according to the electrolysis apparatus 10 according to the present embodiment. . Since the scale is not attached to the cathode 32 in this way, the step of removing the scale attached to the cathode 32 (back washing) can be eliminated or reduced, and continuous operation is possible.

  When only the second discharge valve 38b is opened and the electrolyzed water is discharged only from the second discharge port 38a of the cathode chamber 30, the acidic water generated in the anode chamber 20 flows toward the cathode chamber 30 and has a high concentration. It becomes possible to generate alkaline electrolyzed water containing hypochlorous acid, and no further scale adheres to the cathode 32.

  (2) Conventionally, there was no idea of mixing the electrolyzed water generated in the anode chamber 20 and the electrolyzed water generated in the cathode chamber 30. However, the inventors of the present application have found that by mixing the electrolyzed water generated in the anode chamber 20 and the electrolyzed water generated in the cathode chamber 30, the mixed water exhibits weak alkalinity, neutrality or weak acidity. . Also, by mixing these electrolyzed water, conventionally only one electrolyzed water was used and the other electrolyzed water was discarded, but since both electrolyzed water can be used, water resources are effective. Can be used for

  (3) By adjusting the distribution ratio adjusting valve 60, the amount of current flowing to the water per unit water amount flowing to the cathode 32 can be adjusted. That is, if the amount of current is the same, the amount of current flowing to the water per unit amount of water can be increased if the amount of water is small. The larger the amount of current per unit water flowing through the cathode 32, the more difficult the scale adheres to the cathode 32. Therefore, by reducing the amount of water supplied to the cathode chamber 30, it is possible to more reliably reduce the scale on the cathode 32.

  (3) The first and second water supply ports 26 and 36 are provided above the anode chamber 20 and the cathode chamber 30, and the first and second discharge ports 28a and 28b are provided below the anode chamber 20 and the cathode chamber 30. By flowing water from the top to the bottom, the chlorine generated at the anode 22 hardly rises upward, and the time for the chlorine to contact the water can be lengthened. Therefore, the reaction to hypochlorous acid can be realized more reliably.

  (4) Normally, when the amount of distribution to the anode chamber 20 is low, when the electrolyzed water generated in the anode chamber 20 and the electrolyzed water generated in the cathode chamber 30 are mixed, hypochlorous acid It appears that the concentration is greatly reduced. However, the present inventor has found that the concentration of hypochlorous acid (effective chlorine concentration) does not greatly decrease in the electrolyzed water obtained by the present embodiment. Therefore, according to this Embodiment, since the electrolyzed water obtained contains high concentration hypochlorous acid, bactericidal power does not fall.

  Hypochlorous acid is generally known to be contained in the acidic electrolyzed water produced on the anode side, but hypochlorous acid whose pH value is adjusted to slightly acidic, neutral or slightly alkaline is known. In the case of producing chloric acid water, hydrochloric acid is added to industrially produced sodium hypochlorite (soda) to adjust the pH value, or acidity including sodium chloride produced by the above-mentioned literature 1 is used. Although it is conceivable to manufacture by mixing an appropriate amount of electrolyzed water and alkaline electrolyzed water, in any case, the pH value is not adjusted independently without changing the effective chlorine concentration so much.

なお、第１の吐出バルブ２８ｂと第２の吐出バルブ３８ｂとを同じ程度開放することで、陽極室２０で生成された電解水と陰極室３０で生成された電解水との混合比率は下がることになるため、混合比率は特に第１および第２の吐き出しバルブ２８ｂ，３８ｂで調整することができる。 (5) In the present embodiment, the magnitude relationship between the amount of water supplied to the anode chamber 20 and the amount of water supplied to the cathode chamber 30, and the first discharge valve 28b and the second discharge valve 38b. As shown in Table 1, various pH adjustments can be made in the range from weak acidity to weak alkalinity.

In addition, the mixing ratio of the electrolyzed water produced | generated in the anode chamber 20 and the electrolyzed water produced | generated in the cathode chamber 30 falls by opening the 1st discharge valve 28b and the 2nd discharge valve 38b to the same extent. Therefore, the mixing ratio can be adjusted by the first and second discharge valves 28b and 38b.

  (6) Conventionally, when either one is used, one is discarded, but this manufacturing method makes it possible to avoid wasting valuable water resources.

  (7) Conventionally, sodium hypochlorite could not be produced with a three-chamber electrolysis apparatus. In other words, since sodium ions do not move to the anode chamber and hypochlorous acid does not move to the cathode chamber, sodium ions and hypochlorous acid do not react. No sodium chlorite was produced. However, according to the present embodiment, since there is the communication hole 42, hypochlorous acid and sodium ions react with each other, so that sodium hypochlorite is also generated, and sodium hypochlorite. And mixed water of hypochlorous acid can be produced. Thereby, the mixed electrolyzed water having a cleaning action and a bactericidal action can be realized. Sodium hypochlorite is designated as a food additive designated by the Ministry of Health, Labor and Welfare at the time of this application.

  As a comparative example, it is also conceivable to produce sodium hypochlorite in a two-chamber electrolysis device. This two-chamber electrolysis apparatus is an apparatus in which an anode chamber and a cathode chamber are separated by a diaphragm, and an electrolyte such as sodium chloride is dissolved in water to perform electrolysis. When sodium hypochlorite is produced by a two-chamber electrolysis device, there is a restriction that the concentration of sodium chloride becomes high because sodium chloride is dissolved in water.

  In addition, a method of generating sodium hypochlorite by reacting chloride ions in an alkaline environment by electrolysis is conceivable, but in this case, there is a problem that trihalomethane is generated. However, according to the present embodiment, hypochlorous acid is generated in an acidic anode chamber, and hypochlorous acid is generated by reacting the hypochlorous acid with sodium ions. Occurrence does not occur.

  (8) Since the generation of near-neutral electrolyzed water also realizes conformity to drainage standards and the like without any treatment, there is an advantage that it does not give an environmental load such as environmental pollution.

  (9) Electrolytic hypochlorous acid has the feature of easily neutralizing by contact with organic matter.

  (10) When electrolysis is performed in a state where the anode chamber and the cathode chamber are not in communication, the electrolyzed water discharged from the cathode chamber contains a precipitate (calcium carbonate). However, the inventor performs electrolysis in a state where the anode chamber 20 and the cathode chamber 30 communicate with each other, so that the electrolyzed water discharged from the cathode chamber 30 includes the electrolyzed water that flows into the cathode chamber 30 from the anode chamber 20. Therefore, it discovered that the precipitate did not arise. Thereby, the following effects are produced, for example.

  It is conceivable that the electrolytic water discharged from the cathode chamber is stored in a tank and used as necessary. In this case, if the electrolyzed water contains a precipitate, the deposit adheres to the inner wall of the tank, and it is necessary to wash frequently. In addition, sediment may accumulate at the water intake, preventing water from passing through, which may cause failure. However, if the electrolyzed water does not contain sediment, the deposit does not adhere to the inner wall of the tank and the number of washings can be reduced, and sediment is not collected at the intake port, so water can be reliably secured. .

4). Modifications (1) First Modification The first diaphragm 24 made of an anion exchange membrane can be provided with micropores. The diameter of the fine holes can be set to 30 to 80 μm, for example. In this case, you may comprise the 1st diaphragm 24 with a nonwoven fabric.

  According to this, sodium ions in the electrolyte aqueous solution easily move to the anode chamber 20, and mixed water of sodium hypochlorite and hypochlorous acid is more easily generated.

(2) Second Modification As shown in FIGS. 5 to 9, the cathode 32 can be covered with a sheet 90 that is permeable to water. Examples of the sheet body 90 include a nonwoven fabric and a multi-layered net-like sheet. Thus, when the cathode 32 is covered with a sheet body, the following effects are exhibited.

  By covering the cathode 32 with the sheet member 90, water to be electrolyzed stays in the vicinity of the cathode 32. For this reason, the charge amount with respect to the water staying in the vicinity of the cathode 32 increases. As the amount of charge for water increases, the deposition of cation-based scales is further reduced. As a result, continuous operation is facilitated, and backwashing of the cathode 32 is not required or the frequency can be reduced, so that an electrolytic device more advantageous in industrial applications can be realized. In addition, since the scale can be prevented from growing on the cathode 32 and damaging the ion exchange membrane 54, it can also serve to protect the ion exchange membrane. The anode 22 may also be covered with a sheet similar to the cathode 32.

  The effect will be described more specifically with reference to FIG. The raw water supplied to the electrolytic cell flows at high speed on the electrode plate surface. At this time, especially on the cathode side, the scale adheres to the electrode surface, but the raw water becomes a two-stream zone of a high-speed flow zone and a low-speed flow zone by covering the electrode plate surface with a mesh sheet. Sufficient current can be applied to the low-speed fluid whose mesh is covered on the surface of the electrode. By applying this large amount of current with a simple mesh sheet, it is possible to prevent the scale from adhering to the surface of the cathode side electrode plate by a simple method.

(3) Third Modification In the above embodiment, the anode chamber 20 and the cathode chamber 30 communicate with each other through the communication hole 52 of the partition wall 50. However, as shown in FIG. 54 may be used for communication. The communication path 54 has an advantage that it is easy to grasp the amount of water going back and forth between the anode chamber 20 and the cathode chamber 30. An opening / closing amount adjustment valve 56 can be provided in the communication path 54. With this opening / closing amount adjustment valve 56, the amount of water traveling between the anode chamber 20 and the cathode chamber 30 can be easily adjusted.

(4) Fourth Modification As shown in FIG. 12, a first gas vent 28 c for venting the gas generated in the anode chamber 20 may be provided. Thereby, the gas generated in the anode chamber 20 can be discharged, and the instability of the flow rate due to the gas can be prevented. Further, a second gas vent 38 c for venting the gas generated in the cathode chamber 30 may be provided. Thereby, the gas generated in the cathode chamber 30 can be discharged, and instability of the flow rate due to the gas can be prevented. The first and second vent holes 28c, 38c can be plugged as necessary.

(5) Fifth Modification As shown in FIG. 13, the anode 22 can be an electrode having a claw electrode portion 22a. Similarly, the cathode 32 may be provided with a claw electrode portion 32a. The claw electrode portions 22a and 32a are formed so as to extend from one side of the holes 22b and 32b formed by punching. When punching the electrodes 22 and 32 by punching, the nail electrode portions 22a and 32a can be formed by performing punching so that the electrodes 22 and 32 remain without being cut out. Conventionally, in punching electrodes, the portion opened by punching is discarded, and the remaining area of the electrode is used, but in this method, the area used for electrolysis is about 50% before opening by punching and is in contact with the electrode surface. The amount of water to be halved reduces the electrolysis efficiency. However, by leaving the punched portion of the electrode without cutting out, it is possible to leave all the electrodes before punching (the entire area can be maintained), and the electrolytic efficiency does not decrease. Further, since there are blade portions left by punching, the movement of water on the front and back of the electrode becomes smooth, which also leads to an improvement in electrolysis efficiency. Further, it was confirmed that, at the intercept angle at the base of the blade portion, more bubbles were generated than in the plane portion of the electrode, and a vigorous electrolytic reaction occurred. This is thought to be due to the turbulent flow of water on the front and back sides of the electrodes 22 and 32 due to half punching, leading to an improvement in electrolysis efficiency. That is, the ionic water that has moved from the intermediate chamber 40 to the electrodes 22 and 32 side moves from the punched passage ports 22b and 32b to the electrolytic cell outside the electrodes 22 and 32. The raw water passing outside generates turbulent flow while hitting the claw electrode portions 22a and 32a of the electrodes 22 and 32, and is mixed with ionic water moving from the intermediate chamber 40 and further contacts the electrode plate surface as turbulent flow. Thus, the electrolytic efficiency is improved.

  A known method can be applied as the punching method. The shape of the punching hole may be circular or rectangular.

(6) Sixth Modification As shown in FIG. 14, a first opening / closing valve 58a that determines whether or not to supply water to the anode chamber may be provided. In an ordinary electrolysis apparatus, electrolysis cannot be performed unless water is supplied to both the anode chamber and the cathode chamber. However, according to this embodiment, since the anode chamber 20 and the cathode chamber 30 communicate with each other, water is supplied to the anode chamber 20 through the cathode chamber 30 even when the on-off valve 58a is closed. Thus, electrolysis can be performed by a technique that cannot be performed by a normal electrolysis apparatus. For example, when the first open / close valve 58a is closed and the electrolyzed water is discharged only from the anode chamber 20, the electrolyzed water having strong acidity can be generated.

  Similarly, a second opening / closing valve 58b that determines whether or not to supply water to the cathode chamber 30 can be provided. Even if the second opening / closing valve 58b is closed, if the first opening / closing valve 58a is open, water is supplied to the cathode chamber 30 through the anode chamber 20, which is not possible with a normal electrolysis apparatus. Electrolysis can be performed. For example, when the second opening / closing valve 58b is closed and the electrolyzed water is discharged only from the cathode chamber side, electrolyzed water having strong alkalinity can be generated.

(7) Seventh Modification As shown in FIG. 15, a plurality of electrolyzers 10 may be connected in parallel. That is, a plurality of anode chambers 20 and a plurality of cathode chambers 30 are prepared, and the electrolyzed water discharged from each anode chamber 20 is discharged from a common outlet, and the electrolyzed water discharged from each cathode chamber 30 is You may make it discharge from a common discharge port. According to this modification, a plurality of anode chambers are connected in parallel, and a plurality of cathode chambers are connected in parallel, so that water electrolysis can be processed in parallel and a large amount of electrolyzed water can be generated. It becomes easy to do.

(8) Eighth Modification As shown in FIG. 16, the first modification includes a first communication hole 52a provided on the supply port side and a second communication hole 52b provided on the discharge port side. The communication hole 52a can be made smaller than the second communication hole 52b. The opening ratio of the first communication hole 52a and the second communication hole 52b can be, for example, 0.5: 9.5 to 1.5: 8.5.

  When acidic water generated in the anode chamber enters the cathode chamber through the communication hole, since the first communication hole 52a is small, hypochlorous acid contained in the acidic water is subjected to secondary electrolysis in the cathode chamber. Can be suppressed. That is, while preventing secondary electrolysis of acidic water as much as possible, the acidic water can be mixed with alkaline water and discharged. The first communication hole 52a may be set so that the amount of acidic water that can prevent the scale from being applied to the cathode flows. Experiments have confirmed that calcium carbonate is not produced in alkaline water when acidic water having a pH of around 3.0 is mixed at the cathode with 10% or more of the raw water supplied to the cathode chamber.

  In addition, calcium carbonate has been attached to the inside of piping when alkaline water is used for cleaning or plant activity, or has been caused to cause troubles such as adhesion to the shaft of a water pump and rotation of the pump shaft. However, according to this modification, there is an effect that such a starch composed of calcium carbonate is not generated.

  Furthermore, since there is the second communication hole 52b, a predetermined amount of hypochlorous acid can be moved to the cathode side.

(9) Ninth Modification As shown in FIGS. 17 to 19, the intermediate chamber 40 can be divided into a plurality of sections in the direction in which the anode 22 and the cathode 32 extend. The plurality of compartments of the intermediate chamber can be partitioned by the partitioning portion 42. By partitioning the compartments with the partition portion 42, the electrolyte aqueous solution can be retained, electrolyte ions can be moved more reliably, and efficient electrolysis can be achieved. The plurality of sections of the intermediate chamber 40 can be communicated with adjacent sections. In this case, the supply unit 44 can be provided in each of the plurality of sections. In addition, in each of the plurality of compartments of the intermediate chamber 40, a discharge portion 46 for the electrolyte aqueous solution can be provided. The supply unit 44 and the discharge unit 46 can be realized, for example, by connecting a pipe to a side portion of the intermediate chamber 40.

  (A) The supply part 44 is good also as a supply part for supplying electrolyte instead of supplying electrolyte aqueous solution.

  (B) Each partition of the intermediate chamber 40 may be completely partitioned by the partitioning portion 42. In this case, the supply part 44 which supplies electrolyte aqueous solution to each division, and the discharge part 46 which discharges electrolyte aqueous solution are needed.

  (C) The intermediate chamber 40 can be modified as follows. That is, the main supply part of the electrolyte aqueous solution is provided at one end of the intermediate chamber 40 (one side in the direction in which the anode 22 and the cathode 32 extend), and the other end in the direction in which the anode 22 and the cathode 32 extend. ) Can be provided with a main discharge part for the aqueous electrolyte solution. You may provide the sub supply part for supplying at least 1 electrolyte aqueous solution between the main supply part of electrolyte aqueous solution, and the main discharge part of electrolyte aqueous solution.

  In this case, the anode chamber 20 may be provided with a plurality of sections so as to correspond to the sections of the intermediate chamber 40. This section may be partitioned by the partitioning portion 20a. In addition, each section of the anode chamber 20 may or may not communicate with an adjacent section. Moreover, you may provide the supply part 20b and the discharge part 20c of raw | natural water in each division of the anode chamber 20. FIG. In addition, when each division of the anode chamber 20 is not in communication with the adjacent division, it is preferable to provide the raw water supply unit 20b and the discharge unit 20c in each division. By partitioning the partition by the partition portion 20a, the electrolyte aqueous solution can be retained, electrolyte ions can be moved more reliably, and efficient electrolysis can be achieved.

  If the discharge part of the anode chamber 20 is provided only in the last section, it becomes high-concentration electrolyzed water, and the diaphragm is easily damaged. Therefore, the discharge part 20c is preferably provided in each section.

  The cathode chamber 30 may be provided with a plurality of sections so as to correspond to the sections of the intermediate chamber 40. This section may be partitioned by the partitioning portion 30a. Further, each compartment of the cathode chamber 30 may or may not communicate with an adjacent compartment. Further, the raw water supply unit 30 b and the discharge unit 30 c may be provided in each section of the cathode chamber 30. In addition, when each division of the cathode chamber 30 is not connected with the adjacent division, it is good to provide the supply part 30b and the discharge part 30c of raw | natural water in each division. By partitioning the partition by the partition portion 30a, the electrolyte aqueous solution can be retained, electrolyte ions can be moved more reliably, and efficient electrolysis can be achieved.

  If the discharge part of the cathode chamber 30 is provided only in the last compartment, it becomes high-concentration electrolyzed water, and the diaphragm is easily damaged. Therefore, the discharge part 30c is preferably provided in each compartment.

  According to this modification, the following effects can be obtained.

Conventionally, in a three-chamber electrolysis apparatus, it is not generally performed to produce a large amount of electrolyzed water in one electrolytic cell. The inventor of the present application has found the cause of the problem that a large amount of electrolyzed water cannot be produced in one electrolytic cell as follows. The distance between the anode and the cathode across the intermediate chamber is extremely important in terms of electrical conduction. The shorter the distance between the anode and the cathode, the higher the conductivity. However, since there is an intermediate chamber between the two electrodes, a certain distance is absolutely necessary. Therefore, while there is a limit on the flow rate of the electrolyte flowing into the intermediate chamber, ions from electrolysis move from the intermediate chamber to the anode chamber and the cathode chamber, so that the electrolyte is consumed in the middle of the intermediate chamber, and Na ⁺ or Insufficient Cl- ^{and the} like. That is, the aqueous electrolyte solution flows through a narrow space of about 3 to 6 mm in general between the gap between the anode and the cathode. The saturated aqueous sodium chloride solution conducts electricity most efficiently, but Na ⁺ and Cl ˉ in the electrolyte flowing through the narrow intermediate chamber move to the two electrodes through the ion exchange membrane, and the ions in the intermediate chamber As the concentration passes through the electrolytic cell, the concentration decreases as ions are consumed. As a result, in one large electrolytic cell, the difference in ion concentration between the vicinity of the inlet and the outlet of the electrolyte becomes large.

  A strong voltage is required when the electrolytic ion concentration in the intermediate chamber becomes a certain concentration or less due to exhaustion. However, electrolysis is required at a constant low voltage to prevent power consumption and electrode or diaphragm damage. Therefore, in order to maintain the voltage with the optimum efficiency, the electrolytic area naturally has an appropriate value because of the structure. As a result, the inventor of the present application has recognized the cause of the problem that the problem associated with the mass production of electrolyzed water cannot be overcome.

  This modification is made by paying attention to the cause of this problem. That is, by providing the supply unit 44 for supplying an electrolyte or an aqueous electrolyte solution in the middle of the intermediate chamber 40, the consumed electrolyte can be replenished. Therefore, the electrolyte concentration in each area of the intermediate chamber 40 can be leveled. For this reason, it is possible to suppress unevenness in electrolysis efficiency in each electrolysis part, and to achieve efficient and effective electrolysis. In addition, since the electrolyte concentration can be leveled, driving at a low voltage can be performed, and damage to the electrode and the ion exchange membrane can be suppressed.

As shown in Table 1, it is possible to freely adjust the pH by adjusting the communication mode between the anode chamber and the cathode chamber and the mode of the supply port and the discharge port.

  The electrolyzed water discharged from the anode chamber can be adjusted at least within the range of pH 3.2 to 9.6, ORP 1,120 mV to 20 mV, and hypochlorous acid concentration 40 ppm to 35 ppm. confirmed.
